What is the significance of the error message "Fatal error: Maximum execution time of 30 seconds exceeded" in PHP?

The error message "Fatal error: Maximum execution time of 30 seconds exceeded" in PHP indicates that the script took longer than the maximum allowed time to execute. This can happen when processing large amounts of data or when running complex operations. To solve this issue, you can increase the maximum execution time limit in the PHP configuration file or optimize the code to execute more efficiently.

// Increase the maximum execution time limit to 60 seconds
ini_set('max_execution_time', 60);
